U.K. fossil fuel use for electricity, 2002-2006

From 2002 to 2006, fossil fuel (coal, natural gas, and oil) use for the generation of electricity in the U.K. increased 4.664 mtoe (million tonnes oil equivalent). But electricity generation increased only 0.73 mtoe. This is according to data provided in the 2007 Digest of U.K. Energy Statistics from the Dept. for Business, Enterprise and Regulatory Reform [BERR (formerly DTI, Dept. of Trade and Industry)].

Part of the increase in fossil fuels was due to a decline in nuclear, hydro, and imported sources totaling 2.363 mtoe. That still leaves an increase of 2.301 mtoe in fossil fuel use for an increased electricity supply of only 0.73 mtoe.

That increase of fossil fuels of more than three times the increase of electricity is even more surprising because nonhydro renewables (primarily wind energy) increased 1.655 mtoe in the same period, and other fuels (e.g., burning trash) increased 0.468.

In other words, despite (or because of) building thousands of new wind turbines, the U.K. uses more fossil fuel to generate electricity.

Let's Make Cape Wind History!

I am writing to comment on the Cape Wind Project Draft Environmental Impact Statement (Project ID number: PLN-GOM-0003). Offshore wind promises but is unlikely to deliver an immediate, clean, safe and effective answer to either global warming or energy security. America’s first offshore wind farm, Cape Wind, will generate electricity equivalent to 75% of Cape Cod’s energy needs but without measurably affecting the fuel use of conventional generation plants -- because it is intermittent, highly variable, and to a significant degree unpredictable.

The environmental impacts caused by installing these turbines are undeniable, and they are particularly unjustified when considering the lack of real benefit. From local jobs to clean energy, this project is a harmful boondoggle.

I urge Minerals Management Services to avoid further delay and deny the Cape Wind project in a timely manner.

Less than one-fourth of projected fuel savings from wind on Falklands

It is a simple concept that if wind energy is pushed into the electrical grid, then electricity from another source must be reduced. Wind industry promoters ignore the many factors that complicate the concept and claim that wind-generated electricity equals an equivalent reduction of the displaced source's fuel use.

They ignore the fuel used if a source is simply switched to standby, extra fuel used in ramping up and down in response to wind, and extra fuel burned when a plant operates at lower efficiency because of wind.

They also ignore the significant line loss in transporting wind energy from the remote locations where sprawling facilities are possible. And they ignore the likelihood that in large grid systems, the unpredictable and highly variable wind production is small enough to be simply ignored -- tolerated as a slight rise in line voltage -- especially in the remote areas where wind energy facilities are typically sited -- and allowed to dissipate as heat.

Skeptics point to these factors to try to explain the utter lack of data showing actual reductions of other fuels due to wind on the grid.

But at last -- with no help from wind promoters -- I have found some evidence of fuel savings in a closed island system, where the effect of wind would be most clearly seen.

According to the 2007 issue 4 of Wind Blatt, the Enercon magazine for wind energy, three Enercon E-33/330 kW wind turbines were installed at Sand Bay on East Falkland (Islas Malvinas), where they were expected to provide 20% of the electricity and thus projected to reduce fuel use at the island's diesel-fired plant by 20%. The diesel plant was burning about 4,000,000 liters per year, or about 11,000 liters per day. It provided a maximum load of 3.2 MW in winter and a minimum load of 1.1 MW in summer, with a total annual production of 15,000 MWh (average load 1.7 MW).

In other cases, that's usually the last one reads about fuel savings, but in this case there is a brief follow-up report with actual data.

According to the Falklands government, the wind turbines were officially opened June 29, 2007. On Sept. 20, 2007, they noted that the Sand Bay wind turbines were saving 800-1,000 liters of diesel fuel per day. Wind energy was providing 23% of the electricity at night and 13% during the day (an average of 18%).

But 900 liters is only 8.2% of the previous annual daily fuel use of 11,000 liters. And it is only 4.3% of the daily winter fuel use.

From this admittedly scant information, it appears that although these fast-responding diesel generators may generate 18% less electricity because of wind, they burn only 4-8% less fuel.

Using the winter estimates (the Falklands are in the southern hemisphere), that's a savings of less than one-fourth the amount projected.

Rethinking the Meat-Guzzler

Mark Bittman writes in the "Week in Review", New York Times, Sunday, Jan. 29 (click the title of this post for the complete article):

Though some 800 million people on the planet now suffer from hunger or malnutrition, the majority of corn and soy grown in the world feeds cattle, pigs and chickens. This despite the inherent inefficiencies: about two to five times more grain is required to produce the same amount of calories through livestock as through direct grain consumption, according to Rosamond Naylor, an associate professor of economics at Stanford University. It is as much as 10 times more in the case of grain-fed beef in the United States. ...

If price spikes don’t change eating habits, perhaps the combination of deforestation, pollution, climate change, starvation, heart disease and animal cruelty will gradually encourage the simple daily act of eating more plants and fewer animals.

Tell Congress NOT to extend wind energy Production Tax Credit (PTC)

DO NOT Extend the renewable energy Production Tax Credit

Wind energy facilities currently benefit from having up to 75% of their capital value paid for by taxpayers through not only the 10-year Production Tax Credit, but also 5-year double-declining balance accelerated depreciation, a variety of grants and other incentives, and state and municipal tax breaks. In addition to selling electricity, they are able to sell "renewable energy credits" to further increase their profits.

These facilities are usually developed by developers funded by private investors, increasingly from other countries, who more than welcome such largesse with the public's money. In fact, they clamor for it, pretending it is necessary to their success and that their interests is purely beneficial to all.

Besides the obvious unfairness of this funding, wherever giant wind facilities are constructed, the public has complained of serious ill effects, from loss of natural views, environmental harm, and adverse effects on wildlife and even human health.

DO NOT Extend the renewable energy Production Tax Credit.

Billiary

[Hillary Clinton] is predicting that electing her Democratic rival, Barack Obama, will invite a terror attack because he has less experience than she has. If you wonder if you've heard that kind of argument before, you have. It has been a staple of hardball Republican politics for the past seven years: vote for the Democrats and the terrorists win.

But Clinton deftly purloined it for her own purposes, pivoting a classic Karl Rove tactic against one of her opponents ... Ever since the Clintons' near-death experience in the Iowa vote, their campaign has been playing a very Rovian game. The use of the politics of fear is just the start. In fact classic Rovian tactics are now at the heart of the Clinton campaign.

First, play to your base. Obama continues to appeal beyond core Democrats to independents and even a surprising number of disenchanted Republicans. Clinton decided, in response, to craft her appeal directly to core Democrats: public sector employees, the elderly, working women, the urban middle class. . .

Second, attack your opponent on his strong point ... Obama's biggest strength among Democrats is his early and clear opposition to the Iraq war. And so, following Rove's golden rule, Bill Clinton dismissed Obama's long opposition to the war as a "fairy tale". Because in 2004 Obama had refrained from criticising Kerry's pro-war vote, Clinton argued that Obama implicitly agreed with it. Because he had voted - like so many others - to continue funding the troops, Obama was no different than Hillary. It didn't work. But it was a classic Rove try.

Third, wedge issues. Rove's classic example was same-sex marriage; a way to pit one largely Democratic constituency - gays - against others, namely socially conservative white ethnics and blacks. Hillary Clinton's task in a Democratic primary is much trickier. But gender and race remain potent political tools for the unscrupulous. And she has used both.

Clarity from Greenpeace U.K.

From the Greenpeace e-bulletin, Jan. 17, 2008:
Electricity is not the same as energy. The majority of our energy demand
is for heat and transport. While nuclear power currently accounts for
about a fifth of our electricity generation, that is less than 4% of our
total energy demand.

86% of our oil and gas consumption is used for purposes other than
electricity. Most of the gas we use is for heating and hot water, or for
industrial purposes. Virtually all oil is used for transport. In this
instance, new nuclear power - which can only generate electricity - is
practically irrelevant.

There are real solutions though.

The real solutions to the energy gap and climate change are available
now. Energy efficiency, cleaner use of fossil fuels, renewables and
state of the art decentralised power stations like they have in
Scandinavia.

We can also decrease our oil dependence by improving vehicle efficiency,
public transport systems and reducing the need to travel, especially for
business by using new technology like video conferencing.
Let us hope such a clear view about nuclear power as "practically irrelevant" in fighting global warming extends to industrial wind power, which is even more so.
